Summary

  • use CPython 3.10 for every fixed fbuild CI/action interpreter
  • retain abi3-py310 as the public Python ABI baseline
  • regenerate and validate the uv lock with CPython 3.10

Verification

  • uv lock --python 3.10 --locked
  • soldr cargo test -p fbuild-python --test pyo3_policy
  • soldr cargo fmt --all -- --check

A coordinated FastLED consumer PR will lower its resolver and CI baseline to Python 3.10.

Summary by CodeRabbit

  • Changes

    • Python 3.10 is now the minimum supported version for installation and project configuration.

    • Native builds target the Python 3.10 ABI baseline for improved compatibility with supported environments.
  • Documentation

    • Updated setup guidance to reflect Python 3.10 as the default and minimum supported version.
  • Tests

    • Added checks to ensure Python version requirements remain consistent across installation, documentation, and automation.

📝 Walkthrough

Walkthrough

The change sets Python 3.10 as the minimum and default version for installation metadata, setup documentation, and selected CI workflows. A new policy test verifies these requirements and interpreter pins.

Changes

Python 3.10 baseline

Layer / File(s) Summary
Python requirement contracts
install, .github/actions/setup/action.yml, .github/actions/setup/README.md
The minimum Python requirement changes to 3.10. The setup action default and documentation change to Python 3.10.
CI interpreter pins
.github/workflows/audit-ignored-tests.yml, .github/workflows/template_native_build.yml, .github/workflows/validate-boards.yml
The selected workflows use Python 3.10. The native build workflow documents the abi3-py310 baseline and dependency-lock rationale.
Baseline consistency test
crates/fbuild-python/tests/pyo3_policy.rs
A new test checks Python 3.10 requirements and fixed interpreter settings across metadata, documentation, action configuration, and workflows.

The Python 3.10 policy check can miss a future CI interpreter drift. Bind the assertions to the setup-python steps before merging.

Bind the assertion to the actions/setup-python@v6 step.

The three workflow checks use str::contains, so an unrelated step or comment containing python-version: "3.10" can keep the test passing after the setup step changes. Parse the actions/setup-python@v6 step and assert that its with.python-version value is exactly "3.10".
